EdenSherandtheLostRetainer

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!

If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.

If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?

As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.

And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!

YourGumTissueBiotypeCouldDetermineHowGumDiseaseAffectsYou

Periodontal (gum) disease can cause a number of devastating effects that could eventually lead to tooth loss. However, you may be more prone to a particular effect depending on the individual characteristics of your gums.

There are two basic types of gum tissues or “periodontal biotypes” that we inherit from our parents: thick or thin. These can often be identified by sight — thinner gum tissues present a more pronounced arch around the teeth and appear more scalloped; thicker tissues present a flatter arch appearance. While there are size variations within each biotype, one or the other tends to predominate within certain populations: those of European or African descent typically possess the thick biotype, while Asians tend to possess the thin biotype.

In relation to gum disease, those with thin gum tissues are more prone to gum recession. The diseased tissues pull up and away (recede) from a tooth, eventually exposing the tooth’s root surface. Receding gums thus cause higher sensitivity to temperature changes or pressure, and can accelerate tooth decay. It’s also unattractive as the normal pink triangles of gum tissue between teeth (papillae) may be lost, leaving only a dark spot between the teeth or making the more yellow-colored root surface visible.

While thicker gum tissues are more resilient to gum recession, they’re more prone to the development of periodontal pockets. In this case, the slight gap between teeth and gums grows longer as the infected tissues pull away from the teeth as the underlying bone tissue is lost. The resulting void becomes deeper and more prone to infection and will ultimately result in further bone loss and decreased survivability for the tooth.

Either of these conditions will require extensive treatment beyond basic plaque control. Severe gum recession, for example, may require grafting techniques to cover exposed teeth and encourage new tissue growth. Periodontal pockets, in turn, must be accessed and cleaned of infection: the deeper the pocket the more invasive the treatment, including surgery.

Regardless of what type of gum tissue you have, it’s important for you to take steps to lower your risk of gum disease. First and foremost, practice effective daily hygiene with brushing and flossing to remove bacterial plaque, the main cause of gum disease. You should also visit us at least twice a year (or more, if you’ve developed gum disease) for those all important cleanings and checkups.
